What sales tax applies to your fees in Quebec?

5% GST plus 9.975% QST, as of October 2026, on fees in Canadian dollars.

Do you work in French?

This site is in English. If you need French-language deliverables or meetings, raise it in your first message so we can confirm how the engagement would run before you commit.

Does the CCQ framework change how you plan capacity?

It shapes it. Construction-industry labour in Quebec has its own certification and rules, which affect who you can hire and how you staff projects. We build your capacity plan within that framework; questions about the rules themselves go to the CCQ.

Consulting for Mechanical Contractors in Quebec

Quebec is unlike any other mechanical market in Canada. Most homes are heated with electricity, construction-industry labour runs under a province-specific framework, contractors need an RBQ licence with the right subclasses, and customer-facing material must meet French-language requirements. For a mechanical contractor, those differences shape everything from service mix to hiring.

The Quebec market for mechanical firms

Montréal, Québec City, Laval, Gatineau, Longueuil, Sherbrooke, Lévis and Saguenay are the largest markets. Montréal and its suburbs hold dense multi-residential and commercial work; Québec City and the regional centres have their own strong construction and service markets.

The heating mix is the key difference. According to Statistics Canada, 70% of Quebec households used electricity for primary heat in 2023, with natural gas at 5% and wood at 4%. Gas furnace service is a smaller share of residential work than in Ontario or the Prairies; heat pumps, hydronic and electric systems, ventilation and plumbing take a larger one.

Seasons and crew planning

The heating season is long almost everywhere, and longer still once you leave the Montréal and St. Lawrence plain for the regions. Construction work has its own seasonal rhythms, including the industry's holiday periods.

For a residential firm, heat-pump installation and service create demand in both the heating and cooling seasons. For a construction firm, the challenge is aligning crews with project schedules inside the labour framework. A capacity and hiring plan has to account for both.

Regulators and bodies to know

For reference only; ask the regulators directly about licensing, labour and language obligations.

The Régie du bâtiment du Québec (RBQ) licenses contractors. Work done for others generally needs a licence with the right subclasses.
The Commission de la construction du Québec (CCQ) oversees construction-industry labour and competency certification.
The CNESST covers workplace health, safety and compensation; its costs belong in your labour burden.
The OQLF explains businesses' French-language obligations, including for advertising, websites and signage.

A quick check: install hours on the heat-pump line

Say your quotes assume 16 field hours for a typical ducted heat-pump install, but your job records show an average of 20. At a loaded labour cost of $72 per hour, those four extra hours cost $288 per install. Across 120 installs a year, that is $34,560 of margin that never appears on a quote. The fix is rarely to work faster; it is to quote the hours you actually use, including the paperwork for grant applications.

Programs shaping demand, as of October 2026

Hydro-Québec's LogisVert program offered grants of up to $6,700 for eligible heat pumps when we checked, calculated per 1,000 BTU/h of capacity, with a higher rate for cold-climate units. Hydro-Québec also referred to the new federal heat pump rebate, announced on 2026-10-08 for launch in 2027. Confirm current terms with Hydro-Québec before quoting them.

Strong heat-pump incentives make the heat-pump line central for many Quebec residential firms. The business question is whether that line is priced from real install hours and callbacks, and whether the paperwork is costed in.

Pricing and tax

Fees for Quebec clients are in Canadian dollars plus 5% GST and 9.975% QST, as of October 2026, per the CRA. The full rate card is on pricing.

How we would approach a Quebec engagement

For a residential firm built around heat pumps, we would start with pricing and estimating for that line, then look at the service mix between installs, service and maintenance. For construction firms, job costing and capacity planning within the CCQ framework come first. If you need French-language deliverables, tell us at the start.
